Tears and snoring in microgravity

Verification: The claim combines two effects and overstates both. In microgravity, tears do not drain downward; surface tension can keep them on the eye and gather them into larger drops, but “a water bubble around the eye” is a simplification, not a universal outcome for every tear. A sleep study of astronauts found substantial reductions in snoring and other sleep-disordered breathing in microgravity, but not complete cessation. A small study does not establish that snoring is impossible in space.

Conclusion: Tears do not drain as they do on Earth in microgravity, and snoring decreased in one study, but “stops completely” is unsupported.
